Global attractivity of solutions of nonlinear delay differential equations with a forcing term Original Research Article

In this paper, we give sufficient conditions for every solution of the delay differential equation x′(t)=−p(t)f(x(t−τ))+r(t),x′(t)=−p(t)f(x(t−τ))+r(t), Turn MathJax on to converge to zero. Our results extend and improve several known results in the literature. An application of our main results to an equation derived from mathematical biology is also given.
